Most podcasting recording software allows you to sort through, name and store your files with ease.
It is then simply a matter of 'authoring' or sending these
to your online webspace so that others can access them.
Again, most podcasting software provides you with the ability to publish
your files to the internet. Many podcasting websites are configured for
people to download audio files in MP3 or WAV format.
There are a number of free podcasting software packages available - refine
your web search to free podcasting software.
